JOSEPH HASKINS, 0F CATLIN, ILLINOIS.

GENERATOR.

To all whom it may concern:

Be it known that I, JOSEPH HASKINs, a citizen of the United States, residing at Catlin, in the county of Vermilion and State of Illinois, have invented a certain new and useful Improvement in Generators, of which the following is a specification.

My invention relates to improvements 1n generators preferably for use in connection with calcium carbid and water to generate acetylene gas.

It is illustrated diagrammatically in one form of the accompanying drawing, where- Figure 1 is an elevation; Fig. 2 is a vertical section; Fig. 3 a detailed elevation; Fig. 4 a detail. 1

Like parts are indicated by like letters in all the figures.

The annular base A is provided about its outer edge with the upwardly extending collar A from which projects outwardly the horizontally disposed flange A and is provided with the centrally disposed inverted cup A in which is mounted the flanged tube A. The collar A rigidly mounted on the tube A within the cup A carries the reservoir A, having adjacent its top the discharge ports A The tube A terminates at its lower end in the conical nozzle A having the passage A discharging into the cup A adjacent its base.

The cylindrical housing B, closed at one end by the cover B is rigidly mounted on the base A and surrounded at its base by the collar A forming the liquid reservoir B which may be filled through the port B in the cover 13 closed by the filler cap 13*. The sleeve B is fixed in position centrally in the cover 13 and contains the sleeve B screw threaded therein. The shaft 13 screw threaded in the sleeve B terminates at one end in the thumb screw B and at the other in the needle valve 13 in opposition to the conical valve seat 13 in the tube A The gas or generating pot or chamber C, provided with the closed bottom C and the annular flange O about the open top is in slidable engagement with the collar A and is provided with the lug C in opposition to the inclined holding hook C projecting from the flange A The packing C is compressed between the flanges C A when the pot C is rotated to cause the lug O to ride up on the inclined hook C The pot O is provided with the inwardly extending an- Specification of Letters Patent.

nular ridge or shoulder G intermediate its two ends and slightly below the base A. The ring C, havingthe downwardly extending collar C carries the basket C and rests upon the shoulder C Carbid or other gas forming substance C is contained within the basket C".

The gas cleaning chamber D is located within the reservoir B and separated therefrom by the wall D and communicates by means of the port D through the base A with the interior of the pot C. The porous strainer D of felt or other suitable substance is located in the port D and extends partially within the chamber D and partially within the pot C. The pipe D extends outwardly from the chamber D through the wall of the housing B, and is closed at its outer end by the cap D having the burner hole D through which the gas tobe consumed escapes. The housing B carries the.

hook. or handle E whereby thelamp may be supported or carried.

It will be evident that while I have shown in my drawing an operative device, still many changes might be made in size, shape and arrangement of parts without departing materially from the spirit of my invention. Iwish, therefore, that my drawing be regarded as in a sense diagrammatic.

The use and operation of my invention are as follows: The upper cylindrical housing is first filled with water or other suitable liquid and the needle valve closed by rotating the valve rod until the needle point sits firmly upon the conical seat. The removable basket in the lower pot is then filled with calcium carbid or any other suitable material and is dropped into the pot. It

"will be observed that when in this position there is an air space all around the basket and the contents nowhere come in contact with the pot. The pot is then slipped up over the base of the reservoir and rotated until the lugs thereon ride up over the hooks on the reservoir, drawing the two tightly together, compressing the packing material between the flanges on the pot and reservoir respectively. The lamp is then ready for operation. The needle valve is slightly opened and the liquid or water allowed to flow from the reservoir through the discharge nozzle into the suspended cup. It fills this cup and overflows from the top through the overflow ports, travels down the side of the cup and drips into the carbid in valve and nozzle are protected from the car bid and the only openings exposed tothe carbid are the comparatively large drip passages or ports in the top of the cup, and

these ports, since they are locateda considerable distance away from the carbid, are protected themselves from it, and thus the danger of the stopping up of the water passages and the cutting off of the water supply by the powdered consumed carbid is entirely disposed of. The use of the basket within the pot forms a more convenient cleansing of it and permits freer circulation of the gas about the carbid. And, moreover, since the basket and its contents are out of contact with the pot, there is less danger of heating of the pot and reservoir by the heat formed when the gas is generated. The use of a removable basket prevents the packing of the moistened and consumed carbid in the bottom of the reservoir, and thus permits convenient and effective cleansing of the generator chamber. 'Moreover, since the carbid mass is open at all points thereabout, it may more evenly be consumed, and will dis charge its gas in a more, even and regular manner than it otherwise would. It will be observed also that the water supply pipes and nozzle are all located out of contact with the carbid, and therefore any deleterious action on the metal which the carbid itself might have is limited entirely to the cup and easily removable basket, and the more delicate or more expensive portions of the apparatus are completely out of contact therewith and come in contact only with the gas itself.

I claim:

1. A generator comprising a liquid reservoir, a cylindrical pocket upwardly projecting from the lower wall of said reservoir and separated from the liquid-containing portion thereof and open at its bottom, a supply pipe projecting downwardly from the upper wall of said pocket, a liquid-coutaining trap or cup mounted on said supply pipe located within and surrounded by said pocket and a carbid-containing housing mounted on said liquid reservoir and of such size as to be substantially completely filled by the carbid.

2. A generator comprising a liquid-containing reservoir, a carbid-containing chamber immediately adjacent thereto and of sufficient size only to contain suflicient carbid for a charge, a horizontal wall separating the liquid-containing reservoir and the carbid chamber, an upwardly-extending boss in said wall, a liquid-containing trap or cup in said boss, a discharge from the upper portion of such cup said discharge being located in and protected by said boss and a liquid supply from the reservoir to the bottom of the cup.
